Browsing: Spitzer Space Telescope

The Spitzer Space Telescope was a pioneering observatory launched by NASA in 2003 to explore the universe in infrared light. By detecting heat emissions rather than visible light, Spitzer unveiled hidden structures in galaxies, revealed the birthplaces of stars and planets, and provided new views of distant exoplanets and cosmic dust. Operating far beyond the capabilities of ground-based telescopes, it offered critical insights into phenomena that are otherwise obscured by interstellar clouds. Even after its mission ended in 2020, Spitzer’s discoveries continue to shape our understanding of the cosmos and inform new generations of astronomical research.
